PERMANENT CALENDAR.

Application filed January 31, 1921.

To all whom it may concern:

Be it known that I, THOMAS QUITMAN HARRISON, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented a certain new and useful Permanent Calendar, of which the following is a specification.

The object of my invention is to provide a permanent calendar which is of simple, durable and inexpensive construction.

More particularly my invention relates to a permanent calendar which is very compacted, and comprises only a few parts which are all simple.

Still another object is to provide a support having a casing of resilient material thereon and rolls mounted between the sides of the casing, the rolls being provided with indicating references which are designed to be displayed for indicating the day, date and month.

Still another object is to so arrange the sides of the casing so that the rolls which are journaled in the walls of the casing are yieldingly held against movement so that when they are once adjusted they will remain in that position until some positive force is used for their movement.

Still another object is to provide a suitably arranged key member which may be engaged when it is desired to rotate any of the rolls which have the indicating references thereon.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the ob ects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my dev ce.

Fig. 2 is a vertical, central, sectional view taken through the same.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail, sectlonal view showing how the sides of the casing engage the rolls; and

Fig. 5is an enlarged detall view of the key member.

In the accompanying drawings I have used the reference numeral 10 to indicate generally a support or back which 1s provided with a raised portion 11. The ralsed portion 11 of the support 10 1s provlded Specification of Letters Patent.

Patented May 1'7, 1921.

Serial No. 441,442.

with an enlarged aperture 12. Near the upper and lower ends of the support 10 I have provided openings 13 through which fastening devices may be extended for fastening the device to a wall or the like.

A casing A of resilient material rests upon the raised portion 11 of the support 10 and is slightly smaller than the raised portion in outline.

The casing A includes a top 14 and side walls 15 and 16. The back of the casing is open; the purpose of which will be hereafter more fully set forth.

The raised portion 11 is provided with slots 17 which are formed by punching in a hook member 18 in the raised portion 11, as illustrated in Fig. 2 of the drawings.

The casing A is provided with a plurality of tongues 19 which register with the slots 17, and are designed to be crimped or bent over the hook members 18 for positively fastening the casing A to the support 10.

The top 14 of the casing A is provided with apertures 20, 21 and 22. Rolls 23, 24, 25 and 26 are received in the casing between the walls 15 and 16, and adjacentto the apertures 20, 21 and 22.

In order to journal the rolls in the casing A I have provided pins 27 and flat key members 28. The walls 15 and 16 are provided with registering openings 29 which serve as bearings for the pins 27 and the key members 28.

Each of the pins 27 are received in one end of the rolls and are extended through the openings 29 in the wall 16. The key members 28 are received in the free end of the rolls and are received in the openings 29 in the wall 15.

The key member 28 forms a finger engaging member which may be engaged for rotating the rolls.

The roll 23 is provided with a band or cover 30 which has printed or stamped thereon the days of the week. Friday is shown in Fig. 1 of the drawings as being the day displayed through the aperture 20.

The roll 24 is provided with a band 31 similar to the band 30 and has printed thereon the twelve months of the year, referred to by the reference character 32. The number of the month is referred to by the reference 33, and is placed on one side of the month 32.

On the opposite side of the month 32 are the days 34 which indicate the number of days that are in that particular month. For example January is the first month and has thirty-one days.

The rolls 25 and 26 are designed to operate in cooperation with each other and have wound thereon a band 35 which has one of its ends fixed to the roll 25 and its other end fixed to the roll 26.

The band 35 passes directly below the aperture 22whereby portion of the band will be displayed through the aperture. The band 35 has printed thereon the date 36, numbering from one to thirtyone inclusive. For example February 19 of 1921 is Saturday, and February is the second month of the year.

The key member 28 which operates the roll 23 is rotated to position where Saturday will be displayed through the aperture 20. The key member 28 which operates the roll 24 will be rotated until the month February is displayed through the aperture 21.

The key member 28 which operates roll 25 and 26 may be moved in either direction so that the band which has the dates thereon is moved to position where the date 19 will be displayed through the aperture 22.

From the construction of the parts just described it will be seen how my device is operated and when once set for the day requires only a slight operation to bring the following day to position where it will be displayed.

In order to provide some means for holding the rolls against accidental rotary movement I have provided adjacent to the bearings or openings 29 ribs 37 which frictionally engage the ends of the rolls of my device.

It will be understood that the casing A is made up of resilient material and anchored to the support 10; this prevents any outward springing of the sides of the casing A so that the ribs 37 may be made to engage the ends of the rolls.

In order to insert the rolls into position they are placed through the aperture 12 in the support 1.0 and into the casing. The pins 27 are extended through the openings 29 and driven into one end of the rolls.

While the key members 28 which are fiat are extended through the openings 29 in the opposite side and driven into the free end of the rolls, the flat key prevents any rotary movement of the key relative to the rolls.

The key member is so provided that its finger engaging portions engages the edge of the bearing or opening in the casing. The engagement helps to prevent the rolls from moving of their own accord.

The frictional engagement of the rolls with the ribs 37 and the key member with the edge of the opening prevents any possible independent movement of the rolls.

When installed the ribs 37 engage both ends of the rolls and frictionally engage them for preventing the "free independent rotation.

This feature of my device is very important since it enables me to make a very simple device, yet very etlicient and not likely to get out of order as the sides of the casing A are anchored to the support which prevents any of their outward swinging movement, and thus tends to hold them under a slight amount of tension which makes it possible to frietionally engage the rolls of my device.

It will be seen that my device can readily and easily be operated, is very neat and very simple to assemble.

Some changes may be made in the construction and arrangement of the parts of my machine without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
